Le Butcherettes are currently at work on a followup to last year's breakout debut, Sin Sin Sin. However, that hasn't kept Teri Gender Bender out of the public eye. The group's charismatic singer/guitarist/keyboardist won over crowds at this year's Coachella Festival with rousing performances, including throwing her keyboard out into the audience. Omar Rodriguez Lopez -- who is also reprising his role as producer and bass player for the band's sophomore album -- will be pulling double duty for these shows, as the permanent bassist for Le Butcherettes in addition to his role as co-founder and guitarist in The Mars Volta.
